An Idiot's Guide to Photoshop
1. Introduction
A lot of people are intimidated by Adobe's Photoshop. At first glance it is confusing, but with
a little help you can quickly be on your way to becoming a Photoshop guru. This is our
introductory guide on how to do basic functions in Photoshop.
Photoshop is a layered graphic editing program; it is a great tool for creating, editing and
manipulating images. Let me give you a little bit of knowledge to begin with. I wish someone
would have explained what layers were in relation to graphic design before I started teaching
Photoshop to myself.
Every new piece of data you add to your image is a new layer, even though you see the
whole image as one; it does not mean you have the whole image selected. So if you are
trying to do something to everything on your screen and it is only affecting one portion of it
you are in the wrong layer. Keep that in the back of your mind as we continue.
A new layer is created for each new action you take. If you use the text tool to add some text
to the image it will create a new layer for it. However, if you edit that layer and change the
font color it is still in the same layer. You can always bring up your layers by pressing F7.
The layer portion of the screen is below. This is the heart and soul of Photoshop so make
sure you really do keep in mind as we discuss other Photoshop areas. We will go into more
detail as we discuss each feature.
I really recommend you read following MakeUseOf article on layers before you begin your
Photoshop tutorial.
http://www.makeuseof.com/tag/adobe-photoshop-how-layers-work.
It is an awesome, very short write-up on everything concerning layers.
Let‟s fire up whatever version of Photoshop you will be using, and get started. I will be using
Photoshop CS3 so there might be some slight differences between our versions. Nothing
major but if you can‟t find a specific option where I tell you it is… look around a little more.
Every feature I will show you can be found in all versions of Photoshop as far back as 6 (The
first version I really got into).
Once the program has fully launched, you will be left with a blank work space.

2. Creating a new document
Your default toolbars will be on your right. To create a blank document you can either hit
(Control + N) or click File  New.
That will give you this dialogue box.
Here is where you define your image's dimensions and resolution.
To start we will create a 400 x 400 pixel box. I like to work in pixels due to my web design
background but if you rather use inches or another unit of measure, then use the drop down
and switch it up.
Now you see a blank box in your workspace along with your toolbar all the way on the right
and the layer bar in between them. Your toolbar contains all of your tools that you can use to
manipulate your image. The layer box shows you what layer you are working in and any
relationship between them.
You will notice you have only layer and it is labeled Background with a lock icon. This is how
every new Photoshop image starts. As you add items to your image new layers will be
created automatically.

3. Using the paint brush tool
Let‟s use the paintbrush tool to draw a smiley face.
Select the tool by clicking on the item in your toolbar, as shown below.
Next we pick our brush's size, called the diameter at the top of the screen.
Now use your mouse and paint a smiley face or something more creative. As soon as you
start painting a new layer is created for you.

4. Using the text tool to add text
Let's add some text to our image by clicking on our Text toolbar item here
Notice that Photoshop creates a new layer for your text as I said before. Type something in
and continue.
After selecting the text tool you can click anywhere on your image and type the word style.
You notice your toolbars at the top of the screen change to have word editing tools like font,
size and color.

5. Using the move tool
After you finish typing in your text, click on the move tool. You can see the move tool circled
in the below shot of the toolbar. Use that arrow to click and move your image around.
Notice that the image does not move, it just moves the text. That's because at the moment
it's the text layer that is selected. You need to pay attention to your layers. It is the most
confusing thing to new Photoshop users. I sound like a broken record but you will thank me
later.

6. Adding layer effects like drop shadow and bevel and emboss
Let‟s click on the text layer and click the effects button below it.
Because we have the text layer selected (you see the big T and the layers name is a portion
of your text.) Now we will give the text a drop shadow and bevel and emboss it like so.
After clicking OK your picture will look like this. Notice the difference in the text's appearance.
Pretty cool huh?
You can go back and mess around with the other effects, don't worry I'll wait.

7. Flattening your image and some background on layers
Now if you go to above menu, press Layer  Flatten image. All of your layers become
merged. No matter how many layers you had, they all become one layer, one image.
At this point, try to use the “arrow” move tool again and see what happens this time. Now the
whole image moves. That's because what was two layers before now became only one. You
can see that the layers column on the right now has only one layer listed. This is what
happens when we flatten our image. When there is one layer it normally says Background on
it with a little lock icon. To unlock the layer simply double click on the lock icon.
Even after the layer is unlocked the image is still in this flattened state and you can’t edit the
text or modify the image.
Now let‟s undo our flattening so we can edit the text again. To do this (Well to Un-Do this –
sorry for the pun) we can use a normal Undo or (Control + Z).
Note: If you wanted to do multiple un-do’s like in Microsoft Word you can’t
just keep hitting (Control + Z) you need to use a different command, called Step
Backwards (or Alt + Control +Z.)
Either way this will simply undoes your last action. It will be like it never happened. Paint the
wrong line, type the wrong text just step backwards.
Click the text tool and click on the text layer you will see that you can edit the text again and
modify your effects. Make some changes and then step back to undo them.

8. Resizing your image
Now say you want to resize your image all you have to do is go to Image  Size and change
it.
Let‟s take a look at this:
12

An Idiot's Guide to Photoshop
8.1 Resizing the canvas
You can do the same thing with the background canvas you are working on. You can enlarge
or shrink your workspace. To do this you would go to Image  Canvas Size. Hit this and you
will get a similar dialogue box to the image size box. You can see it below. It will not affect
your image but if you make the canvas too small some of your image may be hidden.
Play around with the size and make your canvas bigger.
Now I have this smaller image on a bigger canvas.

9. Rotating and Free Transform
Let‟s flatten our image again. Image  Flatten Image. Now do you want to rotate your
image? For this we can use free transform, go to Edit  Free Transform (or hit Control + T)
This is in CS3 in other versions it might be slightly different. My colleague is using Photoshop
Elements and for hit it's Image  Rotate  Free Transform after selecting the option then
click the square hollow box under your image and spin or turn it to your hearts content. You
can flip it and mess around with it. Try it out.
Note: This can also be used to straighten scanned photos.
14

An Idiot's Guide to Photoshop
When you are done “Transforming” your image you will need to click onto another toolbar
item like text or the move tool. This let‟s Photoshop know you are done with transforming and
it will now ask you if you want to commit your changes like this:
Click on apply and it will render your image to your specifications. Click cancel or Don‟t Apply
and it will back out of the changes.
15

10. Combining images. Put your test image on a real background
Let‟s put our smiley face image and text on a different background. Do you have a digital
picture on your computer?
Great! Let‟s use that.
First make sure your image is flattened by going to Image  Flatten image. Then we want to
select a box around our image and cut it out.
For this we will use the box tool as seen below (pressing alt while hitting this tool cycles
through other shapes like a circle) pressing alt while hitting this tool cycles through other
shapes, like a circle or a single column of pixels) .
After you select this tool draw a box with your mouse around your image. Like you see in the
screenshot below.
16
askTheAdmin.com
An Idiot's Guide to Photoshop
Press Control+X or navigate to Edit  Cut. Your smiley face will disappear. You can also
use Edit Copy (or Control+C) to leave the original image.
Now we will open the new image and paste the image we have on our clipboard on top of our
digital picture. We do this by clicking file open (Or Control + O).
Then go to Edit  Paste (or Control V) and your smiley face image and text is now on top of
your digital picture. You can move it around, manipulate it and even give it those same
effects we saw before on text. You can apply them to any layer.
Let‟s flatten our image by again going to Image  Flatten Image.

11. Save For Web
Now we will save it for Internet use by pressing File  Save For Web (or Alt + Shift +
Control + S). That may seem like a long hot key but it is the one I use the most often!
18

12. Cropping
Now if you wanted to cut out the baby from the picture or „Crop’ her out you would use the
same box tool we showed you before to draw a box around her. Like so:
Then hit Control + X to cut and Control + N to open a new document (note: that the size is
already perfect for your cropped image) and then Control + V to paste it to the new blank
document.
19

An Idiot's Guide to Photoshop
Now we would like to crop out the rest of the smiley face and try and match up the
background. Let‟s use that rectangular box tool from the toolbar select what‟s left of the
smiley face and hit delete.

13. Using the fill tool
And we will use the fill tool to fill it a similar color for now.
In a later guide we will show you how to replicate the background to make a new piece of it.
But now let‟s fill it. Click on the eyedropper tool like you see selected below.
13.1 Using the Eye dropper tool to select an exact color for the fill tool
Use the eyedropper tool to select the background next to the white square. It will set you
default color to be that shade of pink.
Now we will select the fill bucket and simply fill in this space like so. You can see the fill
bucket selected in the tool bar below. It looks like a paint bucket being tipped over:
Deselect your selection by clicking on the box tool and clicking on your image… Not to bad
for a first try eh?
21
askTheAdmin.com
An Idiot's Guide to Photoshop
Now say we wanted to make this same image black and white – do you know how simple
that is? All I do is Control + A to select all, Control + C to copy my image and Control + N
to open a new document that will have the black and white version of the image.
Here is where I make a change from RGB color to Grayscale as you see here:
Then I paste my image into this black and white container and bam – black and white image!
22

14. Adding a border
It looks like you are catching on fast! Maybe we can try something a little harder. How about
adding a border to the image? First we will select our entire image by pressing Control + A
then we will hit Select Modify  Border
I choose 10 pixels for my border. Then I make sure the color I want is highlighted on the
color selector and I fill the image. This is what I get.
23

An Idiot's Guide to Photoshop
15. Creating a watermark
Sometimes people want you to know where a specific image came from. Maybe because it is
someone‟s original work or maybe it is confidential information and you want to label it as
such. This is a very simple trick and can be done with either an image or text.
We will use a text watermark in the bottom right hand corner of our image.
Click on the text tool add the text you want to watermark your image. Then if you look on
your layer box you will see a setting called opacity. This will allow you to see through your
text or image; I usually put it at around 28% and call it a day. You can also add layer effects
to your watermark.
Not to shabby? Impressed by your own work yet? Let‟s keep on going!
24

An Idiot's Guide to Photoshop
15.1 Blur tool
As our final lesson we will Blur an image, Sharpen an image and then smudge an image.
Let‟s look at the Blur tool.
You can see the tool selected in the above shot. You get to choose your brush for this tool
just like for the paintbrush. Hit the blur tool and then paint on your layer and it will blur like so:
If you want to blur just the portion of the image then use the rectangular select tool to select
that portion first. Once you made the selection use the blur tool to blur the image.
25

An Idiot's Guide to Photoshop
15.2 Sharpen Image
Let‟s step back to undo our blurring. Next by clicking the alt key and hitting the blur tool it will
turn into a triangle aka the sharpen tool.
Select it and paint over a portion of the image like so:
It will sharpen your image. You can step back and un-do what you have done. Now play
around with everything you have learned and you are on your way to becoming a Photoshop
guru!
As you might have noticed both Blur and Sharpen tools can be further adjusted to your liking.
That is to say, when you select one of those tools you will be able to further adjust the impact
of the brush by choosing brush size and its strength (see above screenshots).
That is a basic run through on how to open, edit, create, resize and save images for web use
inside Photoshop.
In addition to this there are loads of plug-ins and effects you can use with Photoshop
anything you can imagine you can find out on the internet. Google it and see what you come
up.
Stay tuned for our next installment where we go deeper into image modification and plug-ins.
